Here is the entire list+effects (in no particular order)

Adrenaline Orb–Boosts Speed by one stage when encountering a Pokemon with Intimidate[type] Memory–Makes Sivally and its Multi-Attack move the same type as the memory its holding (I figured it would be way too cumbersome to put in every single memory here, so just imagine any type other than Normal there, and you’ve got the idea)Electric Seed–Boosts the holders Defense by 1 stage when Electric Terrain is in effect.Grassy Seed–Boosts the holders Defense by 1 stage when Grassy Terrain is in effect.Misty Seed–Boosts the holders Special Defense by 1 stage when Misty Terrain is in effect.Protective Pads–Prevents any damage or other side effects to the holder that normally occur when using a physical move on the target.Psychic Seed–Boosts the holders Special Defense by 1 stage when Psychic Terrain is in effect.Terrain Extender–Extends Electric Terrain, Grassy Terrain, Misty Terrain, or Psychic Terrain by an extra 3 turns when the holder activates any of the above terrains.[Type]nium Z–A special crystal that converts any [type] moves into Z-Moves (I did the same thing as above with the memories here, except this one includes Normal)Aloraichium Z–Upgrades Alolan Raichus Thunderbolt into an exclusive Z move.Decidium Z–Upgrades Decidueyes Spirit Shackle into an exclusive Z moveEevium Z–Upgrades Eevees Last Resort into an exclusive Z moveIncinium ZUpgrades Incineroars Darkest Lariat into an exclusive Z moveMarshadium ZUpgrades Marshadows Spectral Thief into an exclusive Z moveMewium ZUpgrades Mews Psychic into an exclusive Z movePikanium ZUpgrades Pikachus Volt Tackle into an exclusive Z movePikashunium ZUpgrades hat-wearing Pikachus Thunderbolt into an exclusive Z movePrimarium ZUpgrades Primarinas Sparkling Aria into an exclusive Z moveSnorlium ZUpgrades Snorlaxs Giga Impact into an exclusive Z moveTapunium ZUpgrades the Tapus Natures Madness into an exclusive Z move
